  • 4X Vpw Hardware help

    So I have a guy working on some hardware for me.

    He has run into an issue activation the 4X Vpw, wondering if any had some knowledge to help out.

    From His latest Email

    PLanet

    Here is where I am.

    Send request to disable normal messaging ---- positive response

    Send Request High Speed Mode ------------------- positive response

    Send Begin High Speed Mode ------------------------ No response at all

    Have not been able to make any more progress. If I send a 4X message to read codes there is no response.



    Question - is this the normal sequence to initiate 4X mode?






    PLanet

    Do you know if the’ Begin High Speed Mode’ has to be sent after the ‘Request High Speed Mode’? I get a positive response to the Request High Speed Mode command but it’s not responding to commands I send at 4X after that.

    Thanks

    Some more info I have from him

    (I have sent him this document) http://planethax.com/PCMcomms.xls

    Yes. After sending the Begin High Speed Mode, I wait for a response but it never comes. I have tried sending the Begin High Speed Mode in both 1X and 4X speeds but never see a response message, and I have a scope on the bus in case the software misses the response.
    Here are the transmitted messages:



    6CFEF12800000 'send request disable normal messaging

    6Cfef1A000 'send request for 4X data

    6CfeF1A100 'send request start 4X data, sent at 4x rate

    Never see response from the last message
    Is there a way to set the PT in monitor mode and use a Hyperterm type app to monitor data?
    I am able to do this with the Elm, but obviously overflows once my Tech2 goings into 4X

      Not here, as I do already have SERIALMON logged loaded the Tech2 with a file.
      I am hoping to use my OBD2 Y cable and the PT AVT Hardware to Monitor exactly what the Tech2 is sending.

      I have done this with the ELM, but it Buffer Overflows as soon as Tech2 enters 4X.

      Since I already have;
      • Seed/Key
      • Bin File
      • and Most Command

      By monitoring Tech2, I can log all Data, then remove the Known commands(seed/key) and my Known File.
      Then all that would be left is the puzzle pieces I still need to iron out.

      This is my hopes anyways.

      I do have the HexTerm now for the AVT, just need to find (if there is one but I imagine it should) the Monitor Command.
